BIGTREETECH Pi Control Board 64bit Quad Core, 1GB DDR3L 40-pin

I'm using it on a basic bedslinger, nothing fancy. It's done what's promised for a year with no lockups, crashes, etc. Wifi on it works fine but I'm not too far from the AP/router or have tons of wifi traffic. Setup went fine with instructions on Utube.

I purchased this to run Octoprint for my SV06. Follow the instructions on GitHub and it works like a charm with an SV06. This was my first foray into Linux, but was very easy with BigTreeTech's installation instructions. They only issue I had was finding the correct port for running a camera, but once I googled how to find your port with terminal, all was golden. This is running with a 32GB sd card and HDMI to mini-hdmi cable plugged into my printer and is a great alternative to Raspberry PIs. I've also had no issues loading Kiauh on it in preparation for Klipper, using the Mac iOS terminal application to connect to it once you've loaded the correct Debian image per BTT instructions. The install is flawless. I'm glad I purchased!

If you want a RPi for running 3D printers using Klipper, but don't want to wait for them to come back in stock, or to shell out $70-$130 USD, this is the best alternative in my opinion. With that said, you have to use BTT's OS on this, so using it for other stuff is a little limited (though still technically possible).

Very reliable, get this without thinking twice!

I ordered one of these a couple days ago- showed up- missing parts as well as the manual/welcome card that they are supposed to come with- most importantly it was missing the red power connector for the 5v Input. Literally THE way to power and program these before installing them. So I returned it and requested a replacement. That one shows up the same- but this time with a filthy duck in there (I mean FILTHY, covered in black stuff) and it is ALSO missing the key component (red 5v power jumper bridge cap) . All the pictures show it on sellers pictures. Customer pictures show it, online shows it- and a gaggle of people on the BTT forum confirmed that it is supposed to come with one as its KEY to even getting it running- leading me to believe these items were returned and sent out again- further I confirmed that this item doesn't work, no connection no nothing. I Swapped over micro sd and did a whole reinstallation on a Pi and another device with no issue just to sanity check and this BTT PI v1.2 is dead. I see the other reviews saying the same thing multiple times- I'm going to say they were correct and buying this item is a silicone lottery- new working item? Or just slap a stamp on the return bin and send em out again- maybe theyll work the 2nd go around. Suspect These items are being shipping and returned in a circle. They couldn't even bother making sure all the hardware was in the package before sending it out!? 2x in a row. Bonus For the Amazon format-Value for money- poor. It has cost me days of machines down now instead of just going with a Pi, memory capacity Is pointless I guess now- the extra functionality of added ports drew me in as its a great idea! Unfortunately I was able to utilize only 0 out of them. 2x in a row. And I didn't hear a noise from it. It was dead silent.
